The members of a drilling derrick, member connections and the whole derrick will be damaged and have defects owing to servicing for a long time, this results in a great effect on the load capacity of the derrick. Along with the lowering of the load capacity of the derrick, the strain parameters of the structure change accordingly. Thereby an ultimate state method for evaluating the residual load capacity based on measured strain parameters is presented. By measurement of strain parameters aided by comprehensive detection including structure deformation measurement, corrosion depth determination and weld detection, the structure and performance of working derrick are inspected, and the residual load capacity of the derrick is evaluated by using the ultimate state theory. 98 working derricks are tested and evaluated by using this method, and the results are satisfactory.

钻井井架因长期使用,各构件、构件间连接及井架整体都会产生不同程度的损伤与缺陷,严重影响井架的承载能力。与承载能力降低的同时,井架结构的应变参数也发生相应的变化。对此,为提高井架的使用安全性,提出以实测应变参数为基础的井架剩余承载能力极限状态评定方法,即采用以应变参数测试为主,辅以结构变形测量、腐蚀测厚、焊缝探伤等综合测试方法检测在用井架结构性能,应用权限状态理论评定在用井架剩余承载能力。应用该方法已测试与评定了98部在用井架,取得了满意的效果。

Based on the techniques of limit equilibrium and limit analysis, the formulae are given to calculate the ultimate bearing capacity of offshore pipeline in soft clay. In the ultimate state, the ultimate bearing capacity should be equal to the loads acted on the foundation. Thus the solutions to pipeline settlement can be deduced. The suitability of proposed method is verified by model test.

根据极限平衡和极限分析方法,建立了软黏土地基土体上海底管道的极限承载力计算公式。当地基处于极限状态时,基础作用于地基的全部荷载应该等于该地基土体的承载能力,根据这一关系式可以推导出海底管道沉降量的计算公式。通过对试验结果的分析,证实所采用的计算方法是可行的。
